Sensor Swap lets you replace a Minut sensor with a different one keeping the same rental unit, the same settings, and the same historical data. The new sensor takes over exactly where the old one left off. No reinstallation, no reconfiguration, no data loss.
When to use Sensor Swap
Low battery rotation
Swap a depleted sensor for a fully charged one without visiting the property to charge it. The most common use case for multi-property managers. | Upgrading from M2 to M3
Replace a legacy M2 sensor with an M3 while keeping all settings, noise presets, and historical data. |
Replacing a faulty sensor
Swap a malfunctioning sensor for a working replacement without losing your rental unit configuration or event history. | Adding a Wired Mounting Kit
Swap an existing battery-powered sensor for one connected to the AC Power Adapter or PoE Adapter kit. All settings carry over automatically. |
Sensor Swap does not require the Minut app on the day of the swap itself — the swap is triggered physically by placing the new sensor on the mounting plate. However, you do need the app to enable Sensor Swap in your organisation settings before the first time you use it.
Enable Sensor Swap
Sensor Swap must be enabled for your organisation before it can be used. Only an Admin can turn it on or off.
Web app
Go to web.minut.com → Settings → toggle Sensor Swap on
Mobile app
Tap Settings → tap Organisation → toggle Sensor Swap on
Once enabled, Sensor Swap stays on for all future swaps until you turn it off. You only need to enable it once.
Compatibility
Sensor Swap works within the same sensor generation or across M2 and M3. The swap carries over all settings but the features available after the swap depend on the new sensor’s capabilities.
Swap Combination | Supported | Settings carry over | Notes |
M3 → M3 | ✓ | ✓ All | Full feature parity |
M2 → M3 | ✓ | ✓ All | M3 features (outdoor mode, smoking detection) become available after swap |
M3 → M2 | ✓ | X Partial | M2 lacks outdoor mode, smoking detection, and other M3-only features; these will stop working after the swap |
M2 → M2 | ✓ | ✓ All | Full feature parity |
Do not swap an M3 for an M2 if the unit is using M3-only features such as outdoor mode or smoking detection. These features will stop working on the M2 replacement and cannot be re-enabled without swapping back to an M3.
How to Sensor Swap
Prepare the new sensor
Before performing the swap, make sure the new sensor is ready. A sensor that is already installed on another account or rental unit must be factory reset first.
Charge the new sensor fully
The new sensor must have sufficient charge for the swap to complete. M3: charge via USB-C. M2: charge via Micro-USB with the power switch set to ON.
Sensor Swap will not work if the new sensor has insufficient battery
Factory reset if previously installed
If the new sensor was previously installed on any account, factory reset it before attempting the swap.
A brand new sensor out of the box does not need a factory reset
Turn the new sensor on
M3: hold the back button until the sensor glows purple and you hear the audio cue “Ready to install.”
M2: check the power switch on the back is set to ON, then press the main button (the lens) once. Wait for the white circling light to settle; this means the sensor is on and ready.Check firmware is up to date
Both the installed sensor and the new sensor must have the latest firmware for Sensor Swap to work. Firmware updates are applied automatically, but a sensor must be installed and online to receive them. Check the firmware version under Properties → sensor → settings icon (⚙) → Advanced in the mobile app. If the version is outdated, install the sensor normally first to receive the update before attempting a swap.
Perform the Swap
The swap itself is entirely physical; no app interaction is needed during the process. Keep both sensors within 1 metre of each other throughout.
Remove the installed sensor from the mounting plate
Take the currently installed sensor off the wall or ceiling mount. Do not turn it off; it must remain powered throughout the swap process.
Do not turn the installed sensor off; the swap requires both sensors to be on
Attach the new sensor to the mounting plate
Snap the new sensor onto the mounting plate within 60 seconds of removing the old one. The swap starts automatically; both sensors will begin showing a purple circling light.
Keep both sensors within 1 metre of each other during the swap
Wait for the swap to complete
The swap takes up to 60 seconds. When complete, the new sensor lights up green and the replaced sensor fades out. A confirmation event will appear in the log in your Minut app.
Green = swap successful and new sensor is online
Verify the new sensor is online
Press the front button on the new sensor; a green light confirms it is installed and connected. Check the Minut app to confirm the rental unit is monitoring normally with the new sensor.
Troubleshooting
If the new sensor blinks red or does not light up green within 60 seconds, the swap was not successful. A failed swap event will also appear in the app log.
The swap does not start after placing the new sensor on the plate
Confirm Sensor Swap is enabled for your organisation: go to Settings → Organisation → Sensor Swap. Confirm both sensors are powered on. Confirm the new sensor was placed on the mounting plate within 60 seconds of removing the old one. Try again from step 1.
Both sensors show purple but the swap never completes
The sensors may not be detecting each other. Keep them within 1 metre of each other and wait up to 60 seconds. If they still do not complete, check that both sensors have the latest firmware installed. Outdated firmware on either sensor will prevent the swap from completing. See the firmware check in section 4 above.
The new sensor blinks red after the swap attempt
The swap failed. Check that the new sensor has sufficient battery; Sensor Swap will not complete if the new sensor is too low on charge. Charge it fully and try again.
The swap completed but the new sensor shows offline in the app
Press the front button on the sensor to check its status light. A green light means it is actually online; the app may not have refreshed. If it shows white-then-red (M3) or 2 blinks (M2), there is a Wi-Fi issue; see Wi-Fi and connectivity.
I accidentally swapped to an M2 and lost M3 features
Swap back to an M3 sensor. Prepare the M3 as described in section 4 and repeat the swap process. All settings and data will transfer back. The M2 can then be factory reset for future use.
Still having trouble? Email hello@minut.com with both sensors’ serial numbers, the sensor models involved, and a description of what happened. Include the firmware versions from the Advanced settings in the app if possible.
